what's the least expensive unlocked quad-band 3G mobile phone available in the US?

These smart-phones redefines what you can do on a mobile phone. You can tap a number to make a call. Listen to voice mail in any order with Visual Voice mail. 3G gives you fast access to the Internet and email over your cellular network. And 3G makes it easier to multitask: When connected via 3G, you can surf the web even while you’re on a call. What a great invention...
I have put together a selection of inexpensive quad 3G mobile phone's. I hope you relize that with most cell phone provider like T-Mobile, AT&T etc.. you'll get your smart-phone for free with a plan, and you do need a provider...
